I'm in Bristol, UK. Roof mounting not feasible. Thinking to go vertical. Sun only gets to 11 degrees above horizon@winter solstice. Attitude is SSE facing. And yes, it does rain here a lot. (Last week it only rained twice: once for 3 days, and the second time for 4 days - an old joke).
I can go 4 metres wide and 1.7 metres high. The Sun on Dec 21 is only about 4 hours usable -- when it is clear.
Requirements: Run a full size fridge/freezer, iMac 27" 8 hours a day, 6 x 10W LED desk lamps, and a 3000 watt instant electric hot water shower for 15 minutes a day. Possibly also a 900w output room heater (1000 cubic feet) on really cold days - 20 per year - for a couple of hours per day. All of these currently run on 240v UK electricity, and are all fused 13A.
My simple question: Will it work if mounted 11 degrees from vertical to catch max. sun on that day?
No system as yet, seeing if any of you more knowledgeable folks can help with a simple question, which will probably be followed by many more, I am sure.
I think 3or4 x 24v 330 watt mono's, parallel only. Power Jack 8000w LF, 24v to 240v inverter OR Lvyuan 3000/6000 24v to 240v inverter, 24v battery bank, with lots of waterproof space to add additional batteries over time. Only need this set up to last 10 years, then transfer to Nova Scotia, Canada.
Without batteries: cost is about £1500 Sterling. With batteries: 10 x 12V 110AH LEISURE BATTERY, SLA(Calcium) 2s4p: cost is about £2200 Sterling
You will notice there is no charge controller in my list. What amperage would be best for the parameters I have set out?
Thanks. Hope this is enough info to make a reply.
